Graffiti

According to Wikipedia, "graffiti is the unofficial application of graphics on publicly viewable surfaces" such as on building's walls. Although graffiti has a long history with the first apperance in ancient Greek and Romans thousands ago; in this post, I only post artworks of modern graffiti which is an element of the Hip-hop culture.
